There are flightless species of birds on Earth today, but a new study suggests that the amount would be at least four times that of human influence.
The findings were made by a team from the University College College Ledge in London, which is believed to have extinct every bird species since humans first appeared on Earth.
A total of 581 bird species have disappeared from the late Pleistocene 126,000 years ago, and 166 of them lack the ability to fly.
The study determined that flightless birds thrive on most island groups around the world, with special hotspots in New Zealand and Hawaii.
Researchers have also determined that flying birds are more likely to become extinct than those that fly, as it is a simple killer for humans.

Today there are flightless species of birds flying on Earth, but a new study estimates that there will be at least four times as much if not for human influence. These pictures show a group of moors that became extinct due to human predation.
Leading author Dr. Ferran Sayol (UCL Center for Biodegradable Rivers and Environmental Research and University of Gothenburg, Sweden) said: ‘Human influence has led to significant changes in most ecosystems around the world, and has led to the extinction of hundreds of animal species.
‘This can distort evolutionary patterns, especially if flightless-like characteristics are studied in birds, making the species more likely to become extinct. We get a biased picture of how evolution really happens. ‘
For the study, the team has compiled a long list of each known bird that has lived and become extinct over the past 126,000 years.
Then by calculating what each of them was unable to escape from the sky, fixed each.
For the study, the team has compiled a long list of each known bird that has lived and become extinct over the past 126,000 years. Then each of them will be counted as unable to escape from the sky.
Of the 581 bird species, the team reduced flightless to 166 – all of which would still be circulating on Earth if not for humans.
Parties that could not fly were more diverse than previously studied, the study showed.
The findings also confirm that even flightless species are more extinct than flying species.
Co-author Professor Tim Blackburn (UCL Center for Biodiversity and Environment Research and the Institute of Zoology, ZSL) said: ‘Many bird species can become extinct without their normal predator, for example on islands.’
‘Flying consumes a lot of energy which birds can use for other purposes if they do not need to be taken in the air. Unfortunately, however, if humans and their associated rats and cats – suddenly change – this makes them easier prey.

‘Extinction has also often resulted, and the introduction of drones into the global list of endangered animals, compared to avian species, is likely to continue as well.’
Researchers say that most of the island groups had flightless birds before the arrival of humans, occupying ecological structures occupying ecological structures, including Nassiviland (26 species like the extinct Moa) and Hawaii (23 species, all species). Which are extinct, such as flightless geese).
Adding endangered birds to the global picture of bird diversity shows that flightless development in birds occurs at least four times, as we would expect when we only look at live birds.
Dr .. Seoul said: ‘Our study shows that evolution without flight in birds is a widespread phenomenon.
‘Today, most flightless species are penguins, rails or ostriches and their relatives.’
‘Now, only 12 bird families have aircraftless species, but before humans became extinct, the number was at least 40.’
‘Without this extinction we would have shared the planet with the flying owls, the woodpeckers and the ibis, but all of this has now sadly disappeared.’
What do scientists do to bring out clarity?
The process of extinction, or resurrection of an invisible species, is becoming increasingly common among researchers.
Cloning is the most common form of de-extinction, but scientists can also slip ancient DNA sequences into the eggs of a living species.
Harvard researchers believe they will be able to use this method to reverse the extinction of small shrubs.
Scientists are also close to bringing Dudu out of extinction.
A scientist has placed a reconstructed model of the dodo (right) next to the skeleton of an extinct bird in 1938. The flightless bird became extinct in the late 1600s.
The dodo is a flyless bird that became extinct in the late 1600s on the island of Mauritius, east of Madagascar.
With the exception of Dodo, scientists are trying to revive the passenger pigeon, a wild pigeon that became extinct in the early 1900s.
Passenger pigeons lived mainly in North America, mainly around the Great Lakes.
Scientists have also reconstructed the genome of the Tasmanian tiger, which is native to Australia, Tasmania and New Guinea.
It is believed to have become extinct in the 20th century and its stripes are known for its lower back.
